Adding a separate display is a good idea for desktop use, since a) the screen isn't that big, and b) the dock only has a limited range of viewing angles for the unit. In fact, the tilt action for the dock connector seems mostly for the sake of allowing the unit to mate easily with the dock, not for adjusting the viewing angle. Sitting close to the unit even at maximum tilt feels awkward.

Other options for on-the-go versatility include a Kensington KeyFolio Bluetooth keyboard and case combo. For further ruggedness, you'll eventually be able to add a Griffin Survivor protective case.

A Windows 8 tablet plus a docking station typically equals a notebook -- see the Acer Iconia for an example on that score. The Dell Latitude 10 is a Windows 8 tablet whose optional docking station turns it into a fair substitute for a modest desktop system. The additional business-grade features ramp up the value even further. At the same time, though, the price begins to approach that of better-performing hybrids and Ultrabooks.
